Tripod Head for use with Canon 600mm F4 lens

[Sundowner]

I have just recently purchased a Canon 600mm F4 lens for use with my EOS1Ds MkII, the camera and lens configuration is very heavey (nealy 10kgs). Does anybody have any experience with this lens and what is the best tripod head to use, as my Manfrotto 322RC2 is having problems.
I am mainly using the lens for wildlife photography.

Any thoughts!

Sundowner,

What is your name if you dont mind me asking?

I have the kind of kit you have so may be of some help.

I dont know the 322RC2 head, but I may be able to advise.

Here are a list of heads that will take the weight.

468rc2 Pro ball head will take 10kg or
468rc4 pro ball head will take 16kg or
490rc4 maxi ball head will take 12 kg
229 3d pro head will take 12kg
400 geared head if you have the dosh will take 10kg

Hope that helps
Mark
